should be ≤ 80mm (including the 16mm distance from the
surface of the meter to the lens).
4
）
Make suitable adjustment so that the distance and
diameter ratio between the distance between the
object and the lens of the meter and the surface
diameter of the object being measured is smaller than
8:1 to avoid the measurement result being affected by
such causes as failure to target at the object.
5
）
Clean the surface of the object to get rid of any frost, oil,
grime, etc. before taking measurements.
6
）
Apply masking tape or flat black paint to the surface
before taking measurement If the surface of the object
is highly reflective.
7
）
Larger discrepancy may result if measurement is taken
by the meter through transparent materials such as
glass.
8
）
Steam, dust, smoke, etc. may affect measurements.
